Turbo / GDI Oil Error Towards Oil Used Or Oil OCI ? #5317800 01/09/20 02:58 PM

Let's face it , there's more to an oil than just how a UOA performed ? ... Most modern turbo / GDI engines require a shorter OCI than yesteryear's PFI non - turbo engines (usually between 3,000 to 5,000 miles) . As long as an oil is D1 / Gen 2 rated - is a top tier PPPP , M1 , Valvoline Advanced , Castrol EDGE , etc. going to perform better than Super Tech , QSUD , Maganatec , etc. (all D1 / Gen 2 rated) at the same OCI of betwen 3K to 5K miles ? ... Probably in the case of the Hyundai 2.4L GDI engine it's more important to jump up to 5W30 weight and abide by the 3,750 mile severe service schedule and a D1 / Gen 2 rated oil than to fret about top tier D1 / Gen 2 oil or a mid tier D1 / Gen 2 oil as I'm not using them long enough to matter ? ... *In an extremely well kept 2017 Sadona 2.4L GDI non - turbo my oil looks awful at between 2K to 2.5K miles using Valvoline Advanced . Ditto with M1 , QSUD , PPPP and Castrol EDGE . As one Bob's poster once put it : "The Hyundai 2.4L GDI engine trashes oil like it invented the term" ! Stinky , soot soaked , black oil at less than 3K miles of average suburban driving is my GDI engine reward... So convince me what I'm getting for my money by stepping up to a higher priced D1 / Gen 2 rated synthetic oil in a GDI engine that again , trashes the oil like it invented the term and won't make it past a 4K OCI before the even more nasty , deeper black oil is drained so I can repeat the process ?

Lol OP.

You need some cleaner sentences and break up the paragraph into their own thoughts!

But, just use what makes you happy every 5k miles.

I get what your saying. I'll take it a step farther and say that a d1gen2 oil is not even a must. Ford has spec'd a syn blend in all of their turbo GDI engines with use of an iolm. That gives the possibility of going 10k on a blend with a standard filter and there are millions of them on the road doing just that. I'm thinking of running a blend like motorcraft or even Napa and changing every 3k. I'd just change it and let go, no uoa or anything.

I understand. Oil the one day market grandma OCI drain and fill. I wouldn't never want to go so much as this. Recommend 5w30 GDI premium sauce possible long time.

Seems to be a Hyundai thing. Ford engineers need to teach Hyundai engineers how to make a durable engine running 10k OCIs on semi-synthetic.

I've done a UOA of a Hyundai GDI engine with the "black" oil you describe. It came out very well. Was Mobil one 5w-30 on a 5k interval. Blackstone even recommended 6K change. I'll stick with the 5K, but the black oil tells me the oils doing its job.

*Good to know ... Lots of soot generated in Hyundai GDI engines may give a false impression of the oil quality .
